Genome database

Definition

A genome database is a structured collection of data that stores the genetic information of organisms, including their DNA sequences, gene annotations, and related biological information. These databases play a vital role in understanding plant genome structure and organization by providing researchers with easy access to genetic data, which can be analyzed to uncover insights into gene function, expression, and evolutionary relationships.
